Question

这是我需要解决的问题。

我的数据内容在DemoList类中：

注意： DemoHeader对象包含DemoItem对象的ObservableCollection，而DemoList对象包含DemoHeader对象的ObservableCollection

public enum Type { article, product, material }



public class DemoHeader
{
    private ObservableCollection<DemoItem> _items;

    public ObservableCollection<DemoItem> Items
    {
        get { return _items; }
        set { _items = value; }
    }

    public DemoHeader(string document)
    {
        this._salesOrder = document;
        _items = new ObservableCollection<DemoItem>();
    }

    private string _salesOrder;

    public string SalesOrder
    {
        get { return _salesOrder; }
        set { _salesOrder = value; }
    }
}

public class DemoItem
{
    public DemoItem(string name, Type type)
    {
        this._name = name;
        this._type = type;
    }

    private Type _type;

    public Type Type
    {
        get { return _type; }
        set { _type = value; }
    }

    private string _name;

    public string Name
    {
        get { return _name; }
        set { _name = value; }
    }
}


public class DemoList : ObservableCollection<DemoHeader>//, ICollectionView
{
    public DemoList() 
    {
        DemoHeader dd = new DemoHeader("Doc-1");
        dd.Items.Add(new DemoItem("T-1", Type.article));
        dd.Items.Add(new DemoItem("M-1", Type.material));

        DemoHeader dd2 = new DemoHeader("Doc-2");
        dd2.Items.Add(new DemoItem("P-1", Type.product));
        dd2.Items.Add(new DemoItem("P-2", Type.product));

        this.Add(dd);
        this.Add(dd2);

    }
}

public class DemoHeader { private ObservableCollection<DemoItem> _items; public ObservableCollection<DemoItem> Items { get { return _items; } set { _items = value; } } public DemoHeader(string document) { this._salesOrder = document; _items = new ObservableCollection<DemoItem>(); } private string _salesOrder; public string SalesOrder { get { return _salesOrder; } set { _salesOrder = value; } } } public class DemoItem { public DemoItem(string name, Type type) { this._name = name; this._type = type; } private Type _type; public Type Type { get { return _type; } set { _type = value; } } private string _name; public string Name { get { return _name; } set { _name = value; } } } public class DemoList : ObservableCollection<DemoHeader>//, ICollectionView { public DemoList() { DemoHeader dd = new DemoHeader("Doc-1"); dd.Items.Add(new DemoItem("T-1", Type.article)); dd.Items.Add(new DemoItem("M-1", Type.material)); DemoHeader dd2 = new DemoHeader("Doc-2"); dd2.Items.Add(new DemoItem("P-1", Type.product)); dd2.Items.Add(new DemoItem("P-2", Type.product)); this.Add(dd); this.Add(dd2); } }

XAML：

注意：每个ListBox都有4个CollectionViewSource。

DemoList对象绑定到CollectionViewList x：Key = list 。

这是我需要实施的商业逻辑：

如果选中复选框，我需要将选定的ListBoxItem返回给相应的容器[商品，产品，材料] - 这个逻辑是工作
如果复选框未标记，我需要返回所有项目
[ObservableCollection]的ALL标题对应容器[商品，产品，材料]

我被困在这里，有人可以建议我一个解决方案吗？

因为误会和我糟糕的英语而烦恼。

我上传了一些屏幕以便更清楚。

正如您在屏幕上看到的，我需要实现复选框的行为。取消选中时，每个DemoItem对象必须显示在3个容器中的一个容器中。每个容器都绑定到CollectionViewSource。

使用多选模式ListBox绑定项目？
